INCUBATO R.

SPECIFICATION forming part of Letters Patent No. 735,885, dated'August11, 1903.

Application filed April 23, 1903- will enable others skilled in the artto which it appertains to make and use thesanie.

This invention relates to improvements in incubators.

The object of the invention is to construct. an incubator in which aneven distribution.

of the heat and a perfect ventilation is provided for.

A further object is to provide an incubator which will be simple inconstruction and operation, comparatively inexpensive of production, andthe arrangement and operation of the parts being such as to closelysimulate the natural method of egg-hatching.

With these and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be more fully described, and particularly pointed out in theappended claims. 1

Figure 1 is alongitudinal vertical sectional View of the incubator. Fig.2 is a vertical cross-sectional view. Fig. 3 is a horizontal sectionalview of the same. Fig. iis a detail side elevation of the outsideheat-flues. Fig. 5 is a detail View of the egg-tray.

In the drawings, 1 denotes the body of the incubatorcomprising an outerwall or casing 2 and an inner wall 3, spaced apart on all sides -exceptthe bottom to form a dead-air compartment 3, which entirely surroundsthe inner wall except at the bottom, as stated, and at the lower portionof one end of the casing, as hereinafter described.

4: denotes the egg-tray, arranged near the bottom of the incubator andsupported upon cleats 5, fixed to the inner wall 3. In the con structionof the egg-tray an opeuframe 6 is provided, and to said frame isconnected the edges of a coarse-wire screen 7, the screen being formedso as to slope on all sides toward the center to simulate the form of ahens nest.

Above the egg-tray and about midway be- Serial No. 154,011. (No model.)

tween the same and the top of'theincubator is arranged a frame 8,constructedto incline from the sides of the incubator toward the centerin a substantially V form, and over said frame is stretched a coveringof flannel or similar material forming a partition or diaphragm 9, theobject of which is to hold the heat above the eggs in the tray andpermitthe same to slowly passdownwardly through the flannel to the lowerpart of the incubator. After passing through the flannel diaphragm 9 theheated air is retarded in its further downward flow by the V-shaped"frame 8, which guides it toward the center,- from which as it passesdownward it flows outwardly, so as to cover the entire area of theegg-tray 6. By the use of this retarder and deflector the heat passesdownward and is spread to the several eggs on the tray in a naturalmanner and the natural process of incubation further simulated.

Below the egg-tray and near the bottom of the incubator is arranged aframe 10, covered with a fine-mesh wire-netting, forming a screen ordiaphragm 12. The object of this screen is to retard the passage of theheat to the ventilators in the bottom ofthe incubator and prevent unduedrafts.

13 denotes a ventilating-chamber arranged between the inner and outerwalls at one end arranged upon the bottom of the incubator, one end ofwhich communicates with the chamber 13 and the opposite ends of whichopen into the bottom of the egg-chamber of the incubator, as shown. ber13 is out off by strips 13, arranged between the inner and outer walls 2and 3 from the dead-air space 3 15 denotes a vent arranged. in thebottom of the incubator and is adapted to be closed by a plate 16, whichis adapted to slide in ways 17, formed on a plate 18, having a holeformed therein, said plate beingfarranged upon the bottom of theincubator in such manner that the hole therein coincides withthevent-hole 15 in the bottom of the incubator.

19 denotes a heat-conducting flue arranged at one end of the incubator,near the upper end of which is formed alaterally-projecting branch pipeor flue 20, which is adapted to enof the incubator, and 14 denotes fluesor pipes As shown, the said chamter the incubator above the flannelpartition 9. Vithin the branch pipe 20 is arranged ahorizontally-disposed plate 21., which extends partly across the flue19, as shown. The plate 21 serves as a baffle-plate and causes acirculation or breaks the flow of heat from the flue to the incubator.

22 denotes a thimble or ferrule arranged upon and surrounding the branchpipe 20, and between said pipe and the thimble is placed a packing ofasbestos or other protective material 23, the object of which is toprevent overheating of the woodwork of the incubator where the branchpipe 20 enters the same.

22L denotes a hood or bell which is adapted to surround and to besupported upon the flue 19 near the lower end of the incubator. 25denotes a branch pipe projecting laterally from the hood or bell 24, thepipe 25 entering the ventilating-chamber 13 of the incubator and beingprovided with a surrounding packing and thimble 26 and 27, similarto thearrangement on the pipe 20. An annular series of holes 28 is formed inthe upper portion of the hood 24, the object of which is to permit theescape of the heat at this point.

29 denotes a shelf or bracket arranged beneath the lower end of the flue19, being supported in this position by means of an inclined arm 30,having a pivotal connection at its upper end with the under side of theincubator. The shelf is further supported by means of a wire 31,fastened at its upper end to the incubator and connected at its lowerend to the lower end of the arm 30. This method of supporting the shelfpermits the same to be swung to one side to allow the lamp-chimney to beinserted in the lower end of the flue, the shelf being then swung backto support the lamp.

32 denotes the usual damper mechanism arranged on the top of theincubator and automatically controlled by the thermostat 33, arrangedwithin the incubator, as shown.

In operating the incubator the eggs are arranged in the hollow of theegg-tray after the manner of the eggs in a hens nest, the large volumeof heat that is held above the same by the flannel partition ordiaphragm and allowed to slowly pass through the same to the eggssimulating the warmth from the hens body when covering the eggs, aperfect circulation of the airbeing provided for through the ventilating-fiues 14, chamber 13, and hood 24.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. In an incubator, the combination with a casin g having an egg-traysupported therein, of a fabric partition or diaphragm arranged abovesaid egg-tray, means for supplying heated air to the incubator abovesaid fabric diaphragm, means for directing the hot air from said fabricdiaphragm to the center of the incubating-chamber above the egg-tray,and means for permitting the air to escape more or less slowly frombeneath said screen or diaphragm located below said egg-tray,substantially as described.

2. In an incubator, the combinationwith a suitable box or casing of anegg-tray supported in said casing, a fabric partition or diaphragmarranged above said egg-tray, and a screen or diaphragm arranged belowsaid egg-tray, a hot-air flue arranged at one end of said incubator, abranch pipe connecting said hot-air flue with said incubator above saidfabric diaphragm, a ventilating-chamber arranged in one end of saidcasing, ventilating-flues connecting said chamber with the interior ofthe incubator beneath said screen or diaphragm, a hood or bell arrangedupon said hot-air flue, and means for connecting saidventilating-chamber with said hood or bell, substantially as described.

3. In an incubator, the combination with a suitable box or casing of anegg -tray ar ranged in said casing, said tray comprising an open framecovered with a coarse-wire netting sloping in all directions toward thecenter to form a hollow nest-like receptacle, a fabric diaphragmarranged above said eggtray, and a screen-diaphragm arranged below saidegg-tray, means for directing hot air into the incubator above saidfabric diaphragm, and ventilating-fines and a fresh-air vent arrangedbeneath said screen-diaphragm and means for regulating the size of saidfresh-air vent, substantially as described.
